  <div>
   <p>This section describes how to obtain the Keystone V3 address of OpenStack when you need to register OpenStack using the address.</p>
   <div class="section">
    <h4 class="sectiontitle">Procedure</h4>
    <p><strong>For FusionSphere OpenStack, perform the following steps to obtain the Keystone V3 address:</strong></p>
    <ol>
     <li><span>Use PuTTY to log in to any OpenStack node using the management IP address as user <strong>fsp</strong>.</span></li>
     <li><span>Run the following command to switch to user <strong>root</strong>:</span><p></p><pre class="screen">su - root</pre> <p></p></li>
     <li><span>Run the following command to import environment variables, select <strong>openstack environment variable (keystone v3)</strong>, and enter the password:</span><p></p><pre class="screen">source set_env </pre> <p></p></li>
     <li><span>Run the following command to query the Keystone V3 address:</span><p></p><pre class="screen">openstack endpoint list | grep keystonev3</pre>
      <div class="p">
       When command output similar to the following is displayed, the <strong>keystonev3</strong> address whose interface is <strong>public</strong> is the IP address to be obtained. In the example, <strong>https://identity.az236.dc236.huawei.com:443/identity/v3</strong> is the Keystone V3 address to be obtained.
       <pre class="screen">host02:~ # openstack endpoint list | grep keystonev3
| 6894ac66481e46e493c09b76110ec474 | az236.dc236 | keystonev3    | identityv3     | True    | admin     | https://identity.az236.dc236.huawei.com:443/identity-admin/v3         |
| 70b95d31ae75419980442cfae7362d97 | az236.dc236 | keystonev3    | identityv3     | True    | internal  | https://identity.localdomain.com:8023/identity-admin/v3               |
<strong>| 25cb9711e63f420b944d048bddba0d3d | az236.dc236 | keystonev3    | identityv3     | True    | public    | https://identity.az236.dc236.huawei.com:443/identity/v3              </strong></pre>
      </div> <p></p></li>
    </ol>
    <p><strong>For the OpenStack community version, perform the following steps to obtain the Keystone V3 address:</strong></p>
    <ol>
     <li><span>Log in to the management page of the OpenStack community version.</span></li>
     <li><span>In the navigation tree on the left, choose <strong>Admin</strong> &gt; <strong>System</strong> &gt; <strong>System Information</strong>.</span></li>
     <li><span>On the <span class="uicontrol"><b>Services</b></span> tab page of the <span class="uicontrol"><b>System Information</b></span> page, check that the value of <strong>Public</strong> for the Keystone service address is the Keystone V3 address.</span><p></p>
      <div class="note">
       <img src="public_sys-resources/note_3.0-en-us.png"><span class="notetitle"> </span>
       <div class="notebody">
        <p>Due to version differences, if the value of <strong>Public</strong> for the Keystone service address does not end with <strong>/v3</strong>, add <strong>/v3</strong> to the end of the <strong>Public</strong> value to obtain the Keystone V3 address. If the value of <strong>Public</strong> for the Keystone service address ends with <strong>/v3</strong>, the value of <strong>Public</strong> is the Keystone V3 address.</p>
